Fortunately, the real-world search for signs of extraterrestrial civilizations doesn’t have to deal with an alien armada like the one that’s on its way to Earth in “3 Body Problem,” the Netflix streaming series based on Chinese sci-fi author Cixin Liu’s award-winning novels. But the trajectory of the search can have almost as many twists and turns as a curvature-drive trip from the fictional San-Ti star system.

Texas Eclipse Festival offers a 'choose your own adventure experience' for April total solar eclipse
The Texas Eclipse Festival will be unlike any camping experience you've ever imagined with it's "out of this world" lineup of live music, arts, yoga, speakers and more.
'Space headaches' are a literal pain for astronauts. Why do they happen?
Headaches are a common and recurring problem in space, even for astronauts that don't experience them on Earth.
Finding Atmospheres on Red Dwarf Planets Will Take Hundreds of Hours of Webb Time
The JWST is enormously powerful. One of the reasons it was launched is to examine exoplanet atmospheres to determine their chemistry, something only a powerful telescope can do. But even the JWST needs time to wield that power effectively, especially when it comes to one of exoplanet science’s most important targets: rocky worlds orbiting red dwarfs.
The Europa Clipper may only need 1 ice grain to detect life on Jupiter's ocean moon
A single icy moon grain could host tiny microbes or cellular remnants of life. If so, NASA's Europa Clipper may one day be able to find life near Jupiter.
Save nearly $50 on these highly-rated astronomy binoculars
Start stargazing for less — Celestron Skymaster large astronomy binoculars are perfect for skywatching and are currently nearly $50 off on Amazon.
Russian rocket launch of 3 astronauts to ISS targeted for March 23 after abort
A Russian Soyuz rocket is now scheduled to launch three astronauts toward the ISS on Saturday (March 23), two days after a rare abort scuttled its first try.
SpaceX Falcon 9 rocket to tie reuse record with 19th launch tonight
A SpaceX Falcon 9 rocket will launch for a record-tying 19th time tonight (March 22), sending 23 Starlink internet satellites to orbit — if Mother Nature cooperates.
'Quantum tornado' allows scientists to mimic a black hole on Earth
Scientists created a giant vortex made of tiny quantum parts in a helium superfluid just a few degrees above absolute zero. This "quantum tornado" helped them to bring black hole physics down to Earth.
'Shiva and Shakti': The ancient star streams that helped weave the Milky Way
The Gaia space telescope has discovered two ancient stellar streams woven through the heart of the Milky Way, which were present 12 billion years ago.
Boeing's 1st Starliner astronaut flight test for NASA could launch as soon as May 1
Boeing Starliner is ready to carry its first astronaut crew to the International Space Station. Two NASA astronauts will fly on the new spacecraft for a one-week mission in May.

This Week's Sky at a Glance, March 22 – 31
The full Moon goes through a penumbral eclipse. Comet Pons-Brooks nears its best viewing after dusk. As Mercury fades in the sunset, Jupiter becomes the only easy planet in the entire sky.

Europa Might Not Be Able to Support Life in its Oceans
Can Europa’s massive, interior ocean contain the building blocks of life, and even support life as we know it? This question is at the forefront of astrobiology discussions as scientists continue to debate the possibility for habitability on Jupiter’s icy moon. However, a recent study presented at the 55th Lunar and Planetary Science Conference (LPSC) might put a damper in hopes for finding life as a team of researchers investigate how Europa’s seafloor could be lacking in geologic activity, decreasing the likelihood of necessary minerals and nutrients from being recycled that could serve as a catalyst for life.
What Can Europa’s Surface Tell Us About the Thickness of Its Ice?
You can tell a lot about a planetary body just by looking at its surface, especially if it has craters. Take Europa, for example. It has a fairly young surface—somewhere between 50 and 100 million years old. That’s practically “new” when you compare it to the age of the Solar System. And, Europa’s icy crust is pretty darned smooth, with only a few craters to change the topography.
One in Twelve Stars Ate a Planet
That stars can eat planets is axiomatic. If a small enough planet gets too close to a large enough star, the planet loses. Its fate is sealed.
Astronomers call for radio silence on the far side of the moon
There's a growing and passionate call for preserving radio silence on the far side of the moon in order to protect the possibility of conducting valuable radio astronomy.
Dying SpaceX rocket creates glowing, galaxy-like spiral in the middle of the Northern Lights
A large swirl of white light that temporarily outshone vibrant auroras in the Arctic last week was triggered by the death throes of a SpaceX rocket that deployed more than 50 satellites into space.
Historical incidents of viewing total eclipses near the edge of totality
As we prepare for the upcoming solar eclipse on April 8, we take a look at some famous incidents of viewing total eclipses near the edge of totality.
